摘要:汽车无法启动是常见故障,在短时间里寻找故障发生的原因往往相当困难。 故障树分析法作为分析系统
可靠性和安全性的一种重要方法,为复杂系统的故障查找提供了一种有效的途径。 以奇瑞 无法启动为例,建
A3
立了发动机无法启动的故障树模型,设计出了发动机无法启动故障诊断流程图,结合诊断的实际经验与相应的
辅助检查,能够对汽油发动机无法启动故障发生的部位作出快速准确的判断。

Abstract : Electronic-control petrol engine failing to start is a common fault. It is often difficult to find the fault in a short time.
For troubleshooting complex systems , fault tree analysis as the analysis of system reliability and safety is an important method
which provides an effective way. In this paper , taking Chery A3 as an example , the fault tree model of the engine failing to start
is established , the troubleshooting flow chart is designed. Combined
